The study examines the pronunciation of Czech /I/ and /i / in the speech of Czech Radio newsreaders. This vocalic contrast has been traditionally described as consisting in duration. The analyses reveal that the duration of the phonologically long /i / is only approximately 30% greater than that of the phonologically short /I /. As for the analysis of formant values, the short /I / appears to lie closer to vowels of the /e/-quality than to its long counterpart /i /. The morphological status of the syllables with /I/ and /i /, as well as the position within an utterance have been taken into account. The results also indicate interesting idiosyncratic tendencies.
